# Let's Calculate Kinetic Energy!

## What is kinetic energy and how is it calculated?

The kinetic energy of a body is the energy possessed by a body due to its motion. It is calculated using the formula:

**Kinetic energy, KE = ¹/₂mv²**

Where:

**m** is the mass of the object in kilograms

**v** is the velocity in meters per second

Given a body with a mass of 3.4 kg moving at a velocity of 0.5 m/s, what is its kinetic energy?

## Answer

The kinetic energy of the body can be found using the formula:

**KE = ¹/₂ * 3.4 * 0.5²**

KE = 0.425 J

Kinetic energy is a fascinating concept in physics as it relates to the motion of objects. When an object is in motion, it possesses energy known as kinetic energy. The formula for kinetic energy involves both the mass of the object and its velocity squared.

In the given scenario, the body has a mass of 3.4 kg and is moving with a velocity of 0.5 m/s. By plugging these values into the formula, we can calculate that the kinetic energy of the body is 0.425 joules.

It's incredible to see how the mass and velocity of an object play a crucial role in determining its kinetic energy. Understanding kinetic energy helps us analyze the energy dynamics of moving bodies and appreciate the physics behind motion.
